Since nobody else posted it, I might as well give a brief update. You only need to visit one of the 5 BLU's identified in Mhurron's link. Most people agree the Azoulph staging point is the easiest to visit. And given the popularity of the new areas, I was able to easily get there as a level 3 BLM. It seems that most mobs do not aggro, and any that might were all being fought when I strolled through.
